Physics - Converging Lens
Not what you're looking for?
Please solve and explain
Converging lens placed near center of optical bench. Light source and object on left side of lens and screen on the other side.
Light source placed as far away from lens as possible (about 39 cm). The screen is moved until image comes into focus on screen.
Length of object is 6 cm, distance is 25 cm (p) from lens. What would be an estimate (numerical) of the image size and image distance q?
These distances are measured from center of lens.
Come up with numerical estimates (i.e. decreasing p in 2 cm increments) for 8 values of p.
Plot 1/p vs. 1/q (what is y =mx +b)- relate 1/q = -1/p + 1/f
Intercept on 1/p axis? Intercept on 1/q axis?
Focal length from graph of 1/q vs. 1/p?

Converging lens placed near center of optical bench. Light source and object on left side of lens and screen on the other side. Light source placed as far away from lens as possible (about 39 cm). The screen is moved until image comes into focus on screen.
(a) Length of object is 6 cm, distance is 25 cm (p) from lens. What would be an estimate (numerical) of the image size and image distance q? These distances are measured from center of lens.
Data:
Object size, O = 6 cm
Distance of the object from the lens, p = 25 cm
Numerical estimate for the image size, I = 4.4 ...
